Abstract
Abstract. Bose-Einstein correlations in pairs of identical charged pions produced in a sample of 4.3 million Z$$^0$$ hadronic decays are studied as a function of the three components of the momentum difference, transverse (“out” and “side”) and longitudinal with respect to the thrust direction of the event. A significant difference between the transverse, r$$_{t_{side}}$$, and longitudinal, r$$_l$$, dimensions is observed, indicating that the emitting source of identical pions, as observed in the Longitudinally CoMoving System, has an elongated shape. This is observed with a variety of selection techniques. Specifically, the values of the param..
